![]() This is with a simple polled SPI library, not DMA. I now have a new, not SdFat, file system library running well enough to do a first benchmark. I am using a stock Adafruit data logging shield. Wow! The NUCLEO-F401RE is really fast with just polled SPI. Its three 12-bit ADCs can run in interleaved mode to digitize a signal at up to 7.2 MSPS.Įdit: Just checked and Future electronics now sells the 32F429IDISCOVERY for $24.00, about the same as an Uno. The external SRAM has a 16-bit data bus and runs at 80 MHz. 256 KB internal RAM, 8 MB external SRAM, 2 MB flash, 180 MHz clock, 2.4" TFT touch screen. I also bought a 32F429IDISCOVERY board for $33.60. ![]() 4-bit SDIO should be very fast since it should run at 50 MHz. NUCLEO-F401RE : STMicroelectronics : : - ARM Nucleo Board STM32F4 STM32F401RE 512K : NUCLEO-F401RE (PDF) STMicroelectronics NUCLEO-F401RE. I plan to support SD on SPI, SD on 4-bit SDIO, and USB flash drives. I have almost finished porting a new FAT32/FAT16/FAT12 generic file system to the STM32. The 12-bit ADC seems to be very accurate. NUCLEO-F401RE STM32 Nucleo-64 Development Board with STM32F401RE MCU, Supports ST Morpho connectivity Brand: STMicroelectronics 30 ratings Amazon's Choice in Single Board Computers by STMicroelectronics 2816 FREE Returns Available at a lower price from other sellers that may not offer free Prime shipping. I have tested the ADC on these boards and it is at least 50 times faster than the Uno, 2.4 MSPS. There are three SPI controllers, three I2C controllers, and three UARTs. It is faster, 100 MHz, has more SRAM, 128 KB, and 512 KB of flash. STMicroelectronics PCB design board NUCLEO-F401RE STM32 F4 Series Item no.: 1416924 The STM32 Nucleo board provides an affordable and flexible way for users. There is a new NUCLEO-F411RE ($10.33 from Future Electronics). This does not interrupt the connection to the serial monitor since there is a second STM32F103 that handles the serial monitor, programming flash, and debug. Modu z 32-bitowym mikrokontrolerem wyposaonym w rdze ARM Cortex M4, 84 MHz, 512 kB Flash, 96 kB SRAM. I now program flash by drag and drop of the apps. STM32 NUCLEO-F401RE - STM32F401RE ARM Cortex M4. I continue to be pleased with the Nucleo boards. STM Studio reads data through the ST-Link SWD debug port so it does not interfere with the real-time behavior of applications. STMStudio reads the elf file generated by the linker to find and displays variables in real-time. Several people have posted Makefiles templates to build projects generated by STM32CubeMX. NUCLEO-F401RE Mfr. STM32CubeMX creates a project with the generated start-up code and copies needed library code to the project. The power-consumption wizard estimates the application's power usage. The peripherals-and-middleware wizard aids configuration to avoid unusable settings. The user interface is a diagram of the clock tree and you just edit this diagram. The clock-tree wizard assigns clocks and performs dynamic validation. The STM32CubeMX pin-out wizard assists pin assignment to avoid conflicts and has a constraints solver. STM32CubeMX is a graphical configuration tool that automates configuration and generation of STM32 initialization C code. STM32CubeMX - STM32Cube initialization code generator - STMicroelectronics STM32CubeMX is a big improvement over previous ST configuration tools. I have started using STM32CubeMX to configure Nucleo projects and several other STM32 boards.
